Okay it is fun to watch, but there is a bad side to this hitchhiker: eye damage to the koi.

Matt Parker is a Senior Lecturer in Neuroscience and Psychopharmacology, University of Portsmouth, where he studies fish and fish behavior.  Over his career he has some observations about fish and human beings.  I know you will enjoy this easy read, short article on how we humans are like our fellow fish.

A fascinating study suggesting that koi will self-seek water at 90 deg F (32 C) in order to reduce the suffering of KHVD (cyprinid herpesvirus 3). This is very exciting research, but of course as noted by the researchers out of Belgium, a vaccine is still needed.
